Washable electric heating blanket core

Abstract

The present invention discloses a washable electric heating blanket core, and belongs to the field of electric blankets; wherein the washable electric heating blanket core comprises a blanket core and a controller connected to the blanket core by means of a wire, wherein the blanket core is woven from a yarn base material and a heating element, the heating element is composed of heating yarn, and the heating yarn is made of graphene yarn, carbon nanotube yarn, or silver-plated yarn; and positive conductive wires and negative conductive wires are arranged on an upper surface of the blanket core; when the heating yarn employs the graphene yarn or the carbon nanotube yarn, and when the heating yarn employs the silver-plated yarn, the antibacterial effect can be enhanced; wherein the electric heating blanket core can be used in different application scenarios such as blankets and carpets, and is widely used.

What is claimed is: 
     
         1 . A washable electric heating blanket core, comprising a blanket core ( 1 ) and a controller ( 2 ) connected to the blanket core ( 1 ) by means of a wire, wherein the blanket core ( 1 ) is woven from a yarn base material ( 101 ) and a heating element ( 102 ), and the heating element ( 102 ) is composed of heating yarn; and 
       positive conductive wires ( 3 ) and negative conductive wires ( 4 ) are arranged on an upper surface of the blanket core ( 1 ), flame-retardant layers (6) are arranged on the upper surface and a lower surface of the blanket core ( 1 ), moisture-proof layers ( 7 ) are arranged on outer surfaces of the flame-retardant layers ( 6 ), and waterproof layers ( 8 ) are arranged on outer surfaces of the moisture-proof layers ( 7 ). 
     
     
         2 . The washable electric heating blanket core according to  claim 1 , wherein a protective cover ( 9 ) is rotationally connected to an outer surface of the controller ( 2 ) by means of hinges. 
     
     
         3 . The washable electric heating blanket core according to  claim 1 , wherein the flame-retardant layer ( 6 ) is composed of a fireproof basalt fiber cloth. 
     
     
         4 . The washable electric heating blanket core according to  claim 2 , wherein a magnet ( 10 ) is fixedly installed inside the protective cover ( 9 ), and an iron sheet ( 11 ) corresponding to the magnet ( 10 ) is fixedly installed inside the controller ( 2 ). 
     
     
         5 . The washable electric heating blanket core according to  claim 1 , wherein the waterproof layer ( 8 ) is composed of a waterproof nylon cloth. 
     
     
         6 . The washable electric heating blanket core according to  claim 1 , wherein a waterproof silicone insulation layer is arranged on each of outer surfaces of the positive conductive wires ( 3 ) and the negative conductive wires ( 4 ). 
     
     
         7 . The washable electric heating blanket core according to  claim 1 , wherein the heating yarn is made of graphene yarn, carbon nanotube yarn, or silver-plated yarn.
